 Could you try rebuilding your kernel with debug symbols (in the kernel
 config, set 'makeoptions DEBUG=-g' and then either run config -g, or
 if you are using the proper buildworld/installworld procedure, set
 CONFIGARGS=-g in your environment before the buildworld), and then
 try to obtain another dump, so gdb can provide a bit more info?
 
 G'luck,
 Peter
